2 Claims. (Cl. 259-15) This invention relates to mixing and treatment apparatus, and is particularly concerned with the impregnating of solid materials with fluid material. The present illustrative embodiment of the invention is designed for use in impregnating loose or granular or particulate solid material with gas or liquid additive agents.

In present day treatment of solid material, it is common practice to supply thereto liquid or gaseous agents by the use of perforated delivery tubes extending below a bed of pertinent materials. Obviously, in the impregnation of materials by this method, the ports or apertures of the pipes are frequently subjected to clogging and in consequence thereof the homogeneous impregnation of the material is precluded. It is further advantageous in the impregnation or supplying of such materials with additive agents in liquid or gaseous form to provide for constant agitation of the solid material so as to insure homogeneous application of the additive material.

It is therefore among the primary objects of the present invention to provide novel and improved apparatus for the treatment of solid material in granular form to uniformly impregnate the same with liquids and/ or gaseous additive materials.

It is a further object of the present invention to provide a device of the character described by which a constant agitation of the material being treated is maintained so as to insure a uniform and homogeneous distribution of the additive fluid materials.

A further object of the present invention is to provide improved continuously rotating drum type apparatus for the continuous agitation of solid material in particulate while such material is continuously subjected to the discharge of liquid or gaseous additive material.

Ntunerous other objects, features and advantages of the present invention will be apparent from consideration of the following specification taken in conjunction with the accompanying drawing in which:

Fig. 1 is an end elevation of one embodiment of the present invention, a portion thereof being broken away to disclose certain structural details.

Fig. 2 is a side elevation partly in section of the apparatus disclosed in Fig. l.

Fig. 3 is a fragmentary side elevation of the discharge side of the applicating mechanism of the present invention.

Fig. 4 is a cross-sectional view taken on the line 4-4 of Fig. 2.

in general terms, that form of the invention here presented by way of illustration may be broadly defined as comprising a rotary drum provided therein with a relatively fixed fluid discharge member including a longitudinally extending supply device providing a leading edge adapted to engage the solid material as it is lifted by the turning of the drum and further provides a following edge including elongate means constituting passage lips for discharge into the solid material of fluid material. In the present form of the invention, the lips are formed of plastic material extending inwardly to a central longitudinal passage and therein surrounding supply tubes for separate and various types of treatment fluid.

Referring more particularly to the drawing, the rotary chamber is indicated by the numeral 10 and is supported upon rollers 11 disposed on either side of the chamber. Rollers 11 are mounted in suitable brackets 12 extending upwardly from a base 13 and drive mechanism (not shown) is included for imparting rotation to the drum as it is supported by the rollers 11. In that form of the invention here presented, the drum 10 is provided at its left-hand inlet end with a wall 15 having a central aperture 16 which receives therethrough the discharge trough 17 of the material inlet chute 18 through which the loose pulverant or particulate solid material is deposited. The opposite right-hand end of the drum is here shown at 19 as fully open. The material as indicated at 20 is adapted to enter from the trough 17 and pass longitudinally through the drum as it rotates to be discharged through an outlet 21, exhaust aperture 22 is provided through which fumes may escpe.

Stationarily supported through the aperture 16, there is provided a stationary support bar 23 from which depends spaced supporting arm 24, the lower ends of which are formed with companion clamp members 26 adjustably secured by bolts 27. The inner faces of the clamp members 26 are shown as substantially elliptical in form and are adapted to mount therebetween a longitudinally extending agitating and impregnating tube 28. The tube 28 is preferably formed of an upper elliptical member 29 and a companion lower elliptical member 30, as shown in Fig. 4, the upper member being provided with an angularly formed leading edge 31 acting upon the solid material in plow-like manner to insure its passage thereof over on both sides of the tube. The upper and lower members 29 and 30 are overlapped as indicated at 32 to form a. seal precluding the ingress of the solid material within the space 33 formed between such members.

Fluent treatment material is supplied through suitable tubing 34, here shown as three in number, leading to longitudinally extending individual treatment fluid tubes 35, mounted in parallel spaced relation within the chamber 33. Each of the tubes 35 is provided with outlet ports 36 suitably spaced longitudinally thereof, which ports deliver the fluid treatment material to spaces 37 formed by the return bending of plastic discharge sheaths 38. Each sheath 38 extends inwardly from the trailing edge flanges 39 of the upper and lower members 29 and 30 to constitute yieldable fluid discharge lips 40, the spacing of which and yieldability of which are determined by a plurality of transversely extending bolts 41 secured by adjustable nuts 42.

By reference particularly to Figs. 3 and 4 of the drawing, it will be seen that as fluid treatment material is discharged under pressure through the tubes 35 and is emitted from the ports 36 to the chambers 37 between the sides of the sheaths 38, such material will pass outwardly between the lips 49 to be discharged in a longitudinal plane to the solid material passing over the longitudinally extending element 28. It will further be understood that by adjustment of the pressure applied by the nut 42 to the lips 40, the restraint against outward passage of the treatment fluid is readily controlled and thus the amount of impregnation of the solid material by the treatment material may be readily adjusted, as Well as controlled by pressure on the treatment material.

From the foregoing, it will be seen that in the operation of the present device with the solid material discharged into the drum through chute 17 and the drum rotated, the solid material will be lifted upwardly by the rotation of the drum in the direction of the arrow indicated in Fig. 1. Such material will therefore continuously pass g 3 V s over and under the treatment element 28 and in such passage fluid treatment material will continuouslybe' discharged from between the lips 40 into the material, thus uniformly impregnating the same while the agitation. of the material, provides for nnifornrityjand homogeneous character of the materialtreated;

It will of eourse be understood 'that in. the practice of the'jpres'ent" invention, numerous changes, modifications and thefull use of equivalents may be resortedto without departing frornthe spirit orscope of the invention as defined inthe"appended claims;' r
